There are different types of obesity depending on where fat cells are stored. Abdominal obesity, excess fat cell accumulation in adipose tissue of the abdomen, is associated more strongly with meta-inflammation. [9] Evolutionarily, adipose tissue has been shown to function as an immune organ. [8] The immune cells located in adipose tissue are ...
Obesity increases a person's risk of developing various metabolic diseases, cardiovascular disease, osteoarthritis, Alzheimer disease, depression, and certain types of cancer. [36] Depending on the degree of obesity and the presence of comorbid disorders, obesity is associated with an estimated 2–20 year shorter life expectancy.

Death rate from obesity, 2019. Obesity is a risk factor for many chronic physical and mental illnesses.. The health effects of being overweight but not obese are controversial, with some studies showing that the mortality rate for individuals who are classified as overweight (BMI 25.0 to 29.9) may actually be lower than for those with an ideal weight (BMI 18.5 to 24.9).

Elevated leptin concentrations are associated with elevated white blood cell counts in both men and women. [78] Similar to what is observed in chronic inflammation, chronically elevated leptin levels are associated with obesity, overeating, and inflammation-related diseases, including hypertension, metabolic syndrome, and cardiovascular disease.
If an adult (who never was obese as a child or adolescent) gains excess weight, fat cells generally increase in size, not number, though there is some inconclusive evidence suggesting that the number of fat cells might also increase if the existing fat cells become large enough (as in particularly severe levels of obesity). [3] The number of ...
